Struct ViewportConstraints 

pub struct ViewportConstraints {
    pub viewport_size: Option<CanvasSize>,
    pub translate_extent: Option<CanvasRect>,
}

Optional pan constraints for a viewport transform.

Fields

viewport_size: Option<CanvasSize>

translate_extent: Option<CanvasRect>

Implementations

impl ViewportConstraints

pub fn unconstrained() -> Self

pub fn with_translate_extent( viewport_size: CanvasSize, translate_extent: CanvasRect, ) -> Self

Trait Implementations

impl Clone for ViewportConstraints

fn clone(&self) -> ViewportConstraints

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ViewportConstraints

impl Debug for ViewportConstraints

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ViewportConstraints

fn default() -> ViewportConstraints

Returns the “default value” for a type.

impl PartialEq for ViewportConstraints

fn eq(&self, other: &ViewportConstraints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
